My app tells me that ovulation was around 21st Feb so surely it's not possible that these are positive tests already? Unless ovulation was early which symptoms could have indicated day 12/13.

Background: my cycles are usually 31 days with every 3-4 months they jump to 35 days maybe. Lasting 4-5 days long. 28th -31st Dec was one period then 1st-4th was next. I've attached pics if anyone can help. Thanks
